ABB PFSA103B EXCYM322001-EN|Industrial Automation Control Module|

The Multi-Mode Motion Controller is a high-performance servo drive designed to provide precise motion control across a wide range of industrial automation applications.
With rich control modes, flexible configuration options, and comprehensive protection features, it ensures smooth, stable, and reliable operation of servo or stepper motors in both single-axis and synchronized multi-axis systems.Control Modes
External Position Control Mode
Accepts three types of pulse input signals:
Pulse + Direction
CW / CCW (Clockwise / Counterclockwise)
AB Phase Orthogonal Pulse
Enables high-precision external position control through standard pulse train commands.
Internal Position Control Mode
Supports multi-stage programmable positioning point (PPP) control.
The motor can run according to preset position, speed, and acceleration parameters.
Provides up to 8-stage fixed-length control, and each segment can be configured for custom run counts, enabling complex motion sequences without external controllers.
Internal Speed Control Mode
Allows operation at predefined internal speed profiles, selectable via external I/O.
Suitable for standalone applications where consistent speed control is required.
External Speed Control Mode
Achieves continuous speed regulation through external analog voltage commands (0–10V).
Enables smooth acceleration and deceleration under variable process demands.
Touch Speed Adjustment Mode
Motor speed is adjusted proportionally to input trigger pulses, functioning as a digital potentiometer for convenient manual or automatic fine-tuning.
Torque Limit Control Mode
Supports real-time torque control via I/O switches or external analog input (±10V).
Ensures mechanical safety and process stability in tension or pressurization applications.
CANbus Synchronous Control Mode
The master-slave synchronization mechanism automatically adjusts the slave motor’s speed to maintain perfect synchronization with the master, ideal for multi-axis coordinated control.
Mixed Control Mode
Allows the external control terminal to freely switch between two preset control modes, providing enhanced operational flexibility for complex automation scenarios.
